Title: Method and device for separating interrupted position in light transmitting path
Inventor: OKADA KENJI
IPC: G02B5/28
Filed: 1983-04-22
Abstract: PURPOSE:To perform separation of an interrupted position in a light transmitting path used in optical fiber communications, by detecting the amount of reflection of light with a monitoring wavelength, which is inputted at the near end of the light transmitting path under test toward the far end. CONSTITUTION:At a subscriber's end of a light transmitting path 2, a filter 10, which separates light having a signal transmitting wavelength and light having a monitoring wavelength, is provided. A light signal from a signal transmitting circuit 1 is coupled to the light transmitting path 2 by a filter 12 and propagated. The light is separated by the filter 10 at the subscriber's end and received by a light receiving circuit 3. Meanwhile, light from a light-pulse transmitting circuit 7 in a center is inputted to the light transmitting path 2 by the filter 12 through an optical directional coupler 8. The light is selected by the filter 10 at the subscriber's end, reflected by a reflecting mirror 11, transmitted again in the light transmitting path 2 in the reverse direction, and received by a light-pulse receiving circuit 9 through the optical directional coupler 8. Based on the received time and amount of the reflected light, the presence or absence of a broken section and the distance to the broken section can be determined.

Title: Fuzzy controller
Inventor: OOWADA ARIMICHI
IPC: G06N3/00
Filed: 1990-03-20
Abstract: PURPOSE:To easily change an arithmetic function to an OR operation used from conventionally, while realizing an arithmetic function of an average value as a consequent part operation by constituting a consequent part arithmetic means of a hierarchical network structure part to which a value by which an average value of an input signal value is outputted as an internal state value of an internal coupling from an output layer is set. CONSTITUTION:A hierarchical network structure part 20 operates to calculate an average value of an input signal value inputted to an input layer and to output it to an inference value calculating part 19 n accordance with a data converting function prescribed by a hierarchical network structure which said part has by itself and an internal state value allocated to an internal coupling of its hierarchical network structure. In such a way, when an application value of each fuzzy control rule to the same consequent part membership function is inputted as an input signal from an antecedent part arithmetic part 17, a consequent part arithmetic part 18 calculates an average value of its input signal which is inputted and processes it to determine as an application value to its consequent part membership function. Accordingly, the arithmetic contents can be changed freely.

Title: Method for measuring laser durability
Inventor: WATANABE YOSHINORI
IPC: G01M11/00
Filed: 1998-03-06
Abstract: PROBLEM TO BE SOLVED: To provide a device which can evaluate the laser durability of objects to be evaluated with accuracy. SOLUTION: A sample SA is prepared by forming an optical thin film S0 on a transparent substrate S1. The thin film S0 is, for example, a reflection preventing film or half mirror and formed on the incident-side first surface IS of the substrate S1. Nothing is formed on the light emitting-side second surface OS of the substrate S1. The substrate S1 is formed in a wedge-like shape and the angle between the first surface IS carrying the thin film S0 and the second surface OS is adjusted to a prescribed angle or larger. When the substrate S1 is formed in such a wedge-like shape, the standing wave resulting from the reflection on the rear-side second surface OS is not generated and the increase of power density in the substrate S1 caused by an interference action can be suppressed.  Therefore, no damage occurs in the substrate S1 and the laser durability of the optical thin film S0 can be measured and evaluated precisely.
